Abstract
It is possible to form solder joints with mechanical integrity, but not mechanical strength comparable to that achieved by melting the solder, by sintering eutectic tin-lead solder paste where small amounts of eutectic Sn-Bi powder are added to the paste. This increases the rate of sintering through liquid-phase sintering.
